Do I Need a Permit to Build a Shed in Indianapolis?

Do you need a shed permit in Indianapolis?

Indianapolis and Marion County share one consolidated government, so a single agency, the Department of Business and Neighborhood Services (DBNS), handles shed permits across the city. Indiana enforces the statewide Indiana Residential Code (2020 edition, based on the International Residential Code with Indiana amendments), and Indianapolis applies it through a three-tier rule that is easy to get wrong:

• A shed 120 square feet or smaller, less than 15 feet tall, not on a permanent foundation, and with no utility connections needs no permit.
• Between 121 and 200 square feet, you need a structural permit and a drainage permit.
• Over 200 square feet, you add an improvement location permit on top of those two.

A flood zone changes everything: if your parcel is in one, a flood permit is required for any shed, at any size. For how Indiana handles sheds statewide, see our shed permits in Indiana guide, and for the national rules, the complete shed permit guide.

The Indianapolis shed permit stack

The part that surprises homeowners is not whether a shed needs a permit, it is how many. Marion County treats a shed as a small construction project with its own drainage and zoning consequences, so a mid-size shed can need two or three separate permits, and the city issues them in a set order.

• The drainage permit comes first. Marion County requires it for a detached accessory structure of 121 square feet or more, because a new roof and floor change how water moves across your lot. This one catches people; a 12 by 16 shed is not something most owners expect to need a drainage permit.
• The improvement location permit (ILP) comes next, and only for sheds over 200 square feet. The ILP is Indianapolis's zoning permit. It confirms the shed sits in an allowed yard and meets your district's setbacks and lot coverage before any structural review.
• The structural permit is issued last, and it covers the building itself: the framing, foundation, and, if you use engineered roof trusses, a sealed truss packet.

Because the permits are sequential, a missing drainage or zoning approval holds up the structural permit, so start the stack early. A shed 120 square feet or under skips all three, but read the next section first, because zoning setbacks still apply to it.

Where your shed can go: zoning and setbacks

Even a permit-free shed has to obey Indianapolis zoning. Under the Marion County zoning ordinance, an accessory building like a shed must sit in a side or rear yard, never the front, and is generally capped at 15 feet tall. Your zoning district also sets minimum distances from the side and rear lot lines and a maximum lot coverage, and those vary district to district.

Look up your parcel's zoning and setbacks in the city's Indy Rezone ordinance before you place the shed. This matters most for the smallest sheds: because a 120-square-foot shed needs no permit, no city reviewer checks its placement, so the responsibility to meet the setback is entirely yours. Put it too close to the line and a neighbor complaint can still force you to move it.

What a shed permit costs in Indianapolis

Indianapolis prices these permits as flat fees, not as a percentage of the shed's value. Each permit also carries a $32 application fee. For a detached accessory structure the core fees are:

• Structural permit: $42 for a shed of 1 to 200 square feet, or $193 for 201 to 1,000 square feet, plus a structural plan review fee of $85 for 1,000 square feet or less.
• Drainage permit: $121 for a detached accessory structure.
• Improvement location permit: $108 for a new accessory structure (only over 200 square feet).

Add it up and a shed in the 121 to 200 square foot range runs about $280 once the structural permit, plan review, drainage permit, and application fees are counted. A shed over 200 square feet, which also needs the improvement location permit, lands closer to $550 to $600. A shed on a permanent foundation needs footings that reach the local frost line, and any electrical or plumbing to the shed requires its own separate trade permit.

How to apply and get your shed inspected

Apply online through the DBNS residential development permits portal. You will submit two sets of detailed plans plus a site plan that shows the shed and the distance from it to the front, rear, and each side property line. Whoever pulls the permit must be either the property owner or a contractor licensed in Marion County; having the licensed contractor pull it protects you from being on the hook for field violations.

The full fee schedule is on the city's license and permit fees page. Plan on roughly 2 to 4 weeks for review, longer in the busy season, since Indianapolis runs on the slower side for the region. Inspections follow the structural permit; a shed on footings gets a footing inspection before the concrete is poured and a final inspection when the build is done.

Building a shed without a permit in Indianapolis

Skipping the permits is a poor trade. DBNS can issue a stop-work order, require a retroactive permit, and make you uncover footings so an inspector can verify them. A shed that violates a setback or the lot-coverage limit may have to be moved or taken down.

The cost also follows the property. Unpermitted structures surface during home inspections and title work, and buyers routinely ask for open permits to be closed before closing. Permitting a finished shed after the fact costs more than doing it up front, and an unpermitted structure can give a homeowners insurer a reason to deny a claim tied to it.
